电阻抗断层扫描（EIT）是一种无辐射技术，可生成肺的横截面图像。EIT通过图示生物电阻抗的分布来可视化整体和区域通气。在患者胸腔周围有一个电极带，旋转注入一对无害的交流电，可以测量其余电极的电压。这使得能够重建具有通气内的高度动态变化的断层图像。我们报告一位六岁的女性病患，患有囊性纤维化及右肺上中叶完全破坏。进行了肺叶切除术，这是囊性纤维化患者的一种罕见治疗选择，在严重局部破坏的情况下需要考虑。我们展示了与EIT相关的静态（放射学）和动态调查工具（肺功能测定）的术前和术后文档，EIT是该患者组的一种新的无创和无辐射诊断工具。
Electrical impedance tomography (EIT) is a radiation- free technique generating cross-sectional images of the lung. EIT visualizes global and regional ventilation by illustrating the distribution of electrical bioimpedance. With an electrode belt around the patient's thorax, rotating injection-couples of a harmless alternating current allow voltage measurement of the remaining electrodes. This enables the reconstruction of a tomogram with highly dynamic changes within ventilation. We report on a female six-year-old patient with cystic fibrosis and complete destruction of the upper and middle lobe of the right lung. Lobectomy, a rare therapeutic option in patients with cystic fibrosis that needs to be considered in cases of severe localized destruction, was performed. We show a pre-and postoperative documentation of static (radiology) and dynamic investigation tools (spirometry) in correlation with EIT as a new non-invasive and radiation-free diagnostic tool for this patient group.
